  • Example: * Minimalist Exercise - This example illustrates the basics of usage, with a single form field in which the player is invited to type a handful of characters. The text typed is echoed back in the main window. If the player types a number (positive or negative), the input will be interpreted as a number and that too will be echoed.

    You may prefer to do a release build and run this in a standalone interpreter for better performance. If you choose not to release to a standalone file, you may need to type slowly into the field.
